Is it illegal to give away money to followers?

What if I said I would give 1 ETH to a randomly chosen follower this Friday? 

Screw it, let's do it. I'm gonna give someone 1 ETH on Friday. 

Only rule: Must Recast this post with what you'd do with the ETH

If I win, I'm sending an equal portion of ETH to everyone who likes & recasts this

If chosen, I'd evenly distribute the ETH amongst everyone who recasts this post

Ah yes, but since I had this idea first you should like and recast mine instead 🤣
